PROBLEM TO BE SOLVED: To suppress the degradation of a battery.SOLUTION: A controller which controls travel and cargo handling is connected to a display unit mounted in a vehicle body of a forklift. The controller measures a remaining capacity of a battery that serves as a drive source of the forklift and transmits the measured remaining capacity to the display unit. When the measured remaining capacity of the battery is equal to or smaller than an overdischarge determination threshold, the display unit implements a first notification. When integrated time for which the measured remaining capacity of the battery is kept to be equal to or smaller than overdischarge determination threshold is equal to or longer than an integration threshold, the display unit implements a second notification as long as the remaining capacity of the battery is not equal to or smaller than the overdischarge determination threshold but is equal to or smaller than a notification threshold.SELECTED DRAWING: Figure 5

    【課題】バッテリの劣化を抑制すること。【解決手段】フォークリフトの車体に搭載された表示ユニットには、走行や荷役の制御を行うコントローラが接続されている。コントローラは、フォークリフトの駆動源であるバッテリの残容量を計測して表示ユニットに送信する。表示ユニットは、バッテリの残容量が過放電判定用閾値以下のときには、第1の報知を行う。また、表示ユニットは、バッテリが過放電判定用閾値以下に維持された積算時間が積算閾値以上のときには、バッテリの残容量が過放電判定用閾値以下ではない場合でも、報知用閾値以下であれば第2の報知を行う。【選択図】図5
